kotlin獲取屬性

The task is to get system MAC address.

任務(wù)是獲取系統(tǒng)MAC地址。

package com.includehelpimport java.net.InetAddress import java.net.NetworkInterface//Function to get System MAC fun getSystemMac(): String? {return try {val OSName = System.getProperty("os.name") //Get Operating System Nameif (OSName.contains("Windows")) {getMAC4Windows() // Call if OS is Windows} else {var mac = getMAC4Linux("eth0")if (mac == null) {mac = getMAC4Linux("eth1")if (mac == null) {mac = getMAC4Linux("eth2")if (mac == null) {mac = getMAC4Linux("usb0")}}}mac}} catch (E: Exception) {System.err.println("System Mac Exp : " + E.message)null} }/*** Method for get MAc of Linux Machine*/ fun getMAC4Linux(name: String): String? {return try {val network = NetworkInterface.getByName(name)val mac = network.hardwareAddressval sb = StringBuilder()for (i in mac.indices) {sb.append(String.format("%02X%s", mac[i], if (i < mac.size - 1) "-" else ""))}sb.toString()} catch (E: Exception) {System.err.println("System Linux MAC Exp : " + E.message)null} }/*** Method for get Mac Address of Windows Machine */ fun getMAC4Windows(): String? {return try {val addr = InetAddress.getLocalHost()val network = NetworkInterface.getByInetAddress(addr)val mac = network.hardwareAddressval sb = StringBuilder()for (i in mac.indices) {sb.append(String.format("%02X%s", mac[i], if (i < mac.size - 1) "-" else ""))}sb.toString()} catch (E: Exception) {System.err.println("System Windows MAC Exp : " + E.message)null} }//Main Function, Entry Point of Program fun main(args: Array<String>) {//Call Function to get MAC Addressval macAddress = getSystemMac()//Print MAC Addressprintln("System Mac Address : $macAddress") }

Output
